SiR

Sir -- sound is irrelevant

An initialism used when you want to warn people that a video has sound or music is irrelevant to the video. Sounds that weren't initially part of the video would be labeled "SiR" because they have been added on for another effect or purpose.

I just realized that this was an SiR video, the sound effects were added afterward. These aren't the real sounds.

I hate seeing videos that should be labeled SiR because they have loud annoying music in the background that goes over the original dialogue and sounds.

Video title: cute puppies SiR
